IMPROvEMEN-T IN WATER-WHEELS. l

Ncw Haven, in the couutyof -New Haven and State of Connecticut, haveUinvented'a new Improvement in4 Water-Wheels; and l do hereby declarethe following, when taken `in connection with the accompanying drawingsand .the letters ofref'erence marked thereon, to be a full, clear7 andexact description of the saine,v and which said drawings constitute partof this specification, and represent iii- Figure l, a top View;`

Figure 2, a side `View;V and in v Figures 3 and 4, detached viewsenlarged.

This invention relates `to an improvement in that class of water-wheelscommonly used as tub-wheels, or such as have a vertical axis, the objectof the invention being to construct a cheap and durable wheel;

`The inrentiou `consists iu the arrange-meut of a circular plate or'diskupon `a Yertieal'axis, and having arranged upon the surface of the saiddisk parabolic shaped buckets. C V g A is the shaft, upon which larrange a plate or disk,

The Schedule referred to in these Letters Patent vauzd making part4 cfthe same.

wvo- B, which I form from boiler plate, or other suitable sheet metal.

' Then onto the surface of this disk I tix bluckets C, equidistau't fromeach other, and radiating from the center,.the shape of the bucket beingparabolic, a front view of which is shown in fig. 3, and a section .ofthe same on line a: a: in tig. 4.

The water is directed into the bucket about as de-` noted bythe arrow infig. 1. l

The buckets I prefer to vform from sheet metal, struck up and riveted tothe disk, yet the whole may bee-ast in one piece.

The wheel is set in the pit vin like manner as 'the ordinary tub-wheel,and this wheel, being very-cheap, makes a desirable wheel forgrist-mills and other like purposes where small power is required.

I'claim as my inventionlhe disk B, xed upon the shaft A, and provided iwith radial buckets C, of the form and arrangementsubstantially asdescribed.
